Can I change Host LUN ID on vmax?

Jump to solution

Is there any way to change the Host LUN ID once after the devices are created and added to Masking view? Currently my vmax has assigned HLU's from 0 to b....I want to change them to 40 to 4b. If this is not a viable option can any one please let me know or provide a example of how to create a device in vmax by explicitly specifying the HLU.

Thanks in advance!

You can specify the HLU when adding a device into the Storage Group.

symaccess -sid <SID> -name <SG Name> -type storage \

     add devs <symdev> -lun <addr>

or

symaccess -sid <SID> -name <SG Name> -type storage \

     add devs <symdev:symdevs> -lun <(starting) addr>

There seems to be no option to change the lun address but you should be able to remove the devices from the storage group and add them back. (I think the SG can't be empty while in a masking view so you may not be able to do it once for all)

do you want to manually control this assignment every time you add new storage ? A.Y provided you the commands but understand that if you add a new device and do not specify the -lun parameter it will start from 0.
